Another thing especially noteworthy regarding the ethics of Buddhism is that it is the ethics of naturalism. “For the first time in the history of the world,” in the words of Rhys Davids, “Buddhism proclaimed a salvation which each man could gain for himself and by himself in this world, during this life, without the least reference to God or the gods, either great or small.” In this respect Buddhism is somewhat like the present-day socialism of the materialistic school, which ardently proclaims justice, equity, and universal brotherhood, but says nothing about God. III. SOME EXPRESSIONS OF THE ETHICAL SPIRIT OF BUDDHISM [Sidenote: Introductory] Buddhism has been called the Christianity of the Orient. Like Christianity, it has been a great moralizing force in history. Its ethical ideal has been just such a factor in the moral life of the East as the ethical ideal of Christianity has been in the moral life of the West. To portray even in scantiest outline the influence of this ideal upon the different peoples who have accepted it as their standard of goodness, or whose moral codes have felt its modifying effects, would lead us far beyond the limits of our work. In what follows we shall aim at nothing more--after having first remarked the ethical kinship of the Buddhist reform with other contemporary reform movements--than to note briefly the practical outworkings of the ideal in three or four departments of the moral domain. [Sidenote: The ethical relationships of the Buddhist reform] We shall understand best the import for the moral evolution of humanity of that remarkable revolution in Brahmanic India which resulted in the establishment of Buddhism throughout the peninsula and in other countries of the Far East, if we first notice its ethical kinship with other reform movements which, about the close of the sixth pre-Christian century, make a dividing line in the inner histories of so many of the progressive societies and cultures of that age.[287] In Greece Pythagoreanism was rising. This movement was in its essential spirit a social and moral reform. It was an attempt to introduce a true ethics in Greek city life, and to find a basis for morality in the deep intuitions of the human soul.[288] In Israel the Isaiah of the Exile was proclaiming the loftiest ethical doctrines ever taught by Hebrew prophet, and in his interpretation of the moral government of Yahweh was scattering the seed from which was to spring up a new ethical life among men. In Persia the great teacher Zarathustra (Zoroaster), with like vision of moral things, was declaring to the followers of Ahura Mazda that what God requires of men is purity of purpose, truthfulness in word and act, and unceasing warfare against evil within and without. In China the Master, Confucius, reaffirming the teachings of antiquity, was inculcating essentially the same truth--that the sum of true morality is reverence, obedience, and right living.
